DETAILED DESCRIPTION

[0020] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0021] In this embodiment, refer to Figure 1-Figure 5 , a specifically implemented anti-mistouch dial switch includes a shell 1, a push button 2 installed in the shell 1, a guide piece 3 fixed on the push button 2, and a first pin 4 and a second pin 5 respectively fixed on both sides of the shell 1. A protective cover 6 is installed on the upper end of the shell 1, and movable claws 7 are provided on both sides of the protective cover 6. Both sides of the shell 1 are provided with card slots 8 that cooperate with the claws 7. A slide groove for the push button 2 to slide is provided in the shell 1, and the guide piece 3 is fixed to the lower end of the push button 2 by a pin. The protective cover 6 is made of transparent, high temperature resistant and tough plastic material, so that the internal situation can be seen clearly without opening the protective cover. At the same time, the claw 7 can also have a certain elasticity to facilitate the toggle operation. The matching design of the claw 7 and the card slot 8 enables the protective cover 6 to be firmly fixed on the shell 1 and not easy to fall off. As Figure 3-Figure 4As shown, by sliding the push button 2, the guide piece 3 is brought into contact with or disconnected from the second pin 5, thereby sending a signal of 0 or 1 to achieve a control effect.

[0022] Furthermore, the housing 1 and the push button 2 are made of high temperature resistant and wear resistant engineering plastics, and the guide piece 3 and the first pin 4 and the second pin 5 are made of copper plated gold, which makes the conductivity better and also increases the anti-oxidation and corrosion resistance, thereby increasing the service life of the DIP switch.

[0023] Furthermore, the housing 1 includes a combinable end cover 9 and a base 10. The connection between the end cover 9 and the base 10 is designed with an angle, so that the end cover 9 can be firmly fixed on the base 10 without glue or screws, which is convenient for disassembly and assembly and improves production efficiency.

[0024] Furthermore, the push buttons 2 are provided with two or more, so that the corresponding number of dial switches can be selected according to different customer needs to achieve the control effect and save space.

[0025] Furthermore, the protective cover 6 and the housing 1 are respectively provided with a groove 11 and a boss 12 for matching with each other, and a sealing ring 13 is provided in the groove 11. This makes the sealing between the housing 1 and the protective cover 6 tighter, effectively preventing the intrusion of dust and moisture, and improving the stability and reliability of the switch. At the same time, the design of the groove 11 and the boss 12 also makes the installation of the protective cover 6 more stable and not easy to loosen or fall off.

[0026] Furthermore, the housing 1 and the push button 2 are provided with a limiting groove 14 and a limiting block 15 that cooperate with each other. The limiting groove 14 and the limiting block 15 are designed with an arc, which makes it smoother than the traditional tooth-shaped limiting structure, reduces the resistance of the push button 2 during the sliding process, and improves the comfort and smoothness of the operation. At the same time, the cooperation between the limiting groove 14 and the limiting block 15 also ensures the stability and accuracy of the push button 2 during the sliding process, and avoids the push button 2 from being offset or stuck during the sliding process. There is a gap between the limiting groove 14 and the limiting block 15, so that the push button 2 can have a certain buffer space during the sliding process, reducing the risk of damage to the dial switch due to excessive operating force.

[0027] Furthermore, the claw 7 is provided with a paddle 16 extending outward, so that the protective cover is more convenient to move, and the user can easily operate the claw 7 through the paddle 16, so that the opening and closing of the protective cover 6 becomes simple and quick.

[0028] Furthermore, the housing 1 is provided with an indication mark 17, so that the user can clearly know whether the dip switch is in the state of 0 or 1 at the moment, thereby improving the user's experience and avoiding control errors caused by different operation directions and damage to the device.

[0029] The beneficial effects of the utility model are as follows: by installing the protective cover 6 on the housing 1, and by cooperating the claws 7 on the protective cover 6 with the slots 8 on the housing 1, the protective cover 6 is firmly fixed on the housing 1, so that the DIP switch can be prevented from being accidentally touched during the installation and replacement of other components or during use, thereby affecting the normal use of the equipment. It also prevents dust and other impurities from entering the housing 1 and affecting the control signal. Thus, the practicality of the DIP switch is improved.
